glutPassiveMotionFunc really limietd?

Hye,
I’m making a little video games in openGL using GLUT.
it’s a kind of FPS.
my probleme is :
I use a passiveMotionFunc to move the sight like in ordinary games. But when the cursor is a the extrimity of the screen I can’t move any more.

SO is there a solution to initilize the position of mouse, in order to be able to move as I wish.

Thank you .

PS : sorry for my english, I’m french…
but I hope you will understand my problem.

Oh it’s ok, I succeeded using glutWarpPointer();

sorry for the post…
